I am getting COMException due to 80040154 Class not registered while running c# application

I am facing this exception in my c# application:

system.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {10101000-1962-448A-8604-CCCF5ED78826} failed due to the following error: 80040154 Class not registered

Also the CLSID 10101000-1962-448A-8604-CCCF5ED78826 does not exist in HKEY_CLASSES_ROOT in windows7 registry. I have tried changing platform target to x86 for main project in my application, but it did not help.
